Migrating from Physical to VIO environment
Migration of storage from a physical environment to the VIO environment is an offline task. The migration procedure involves stopping the application, unmounting the file systems and deporting the disk group on the physical server. Prior to being deported, you can take a space optimized snapshot, to facilitate fail-back.
Verify that the devices are visible on VIO client and the VFC adapter mapping between VIOS and VIO client is set up correctly. Refer to the IBM documentation for details. After all the required devices are accessible in VIO client 1, import the disk group in the client, mount the file system, and then start the application on the VIO client 1.
Refer to IBM documentation on how to configure the VFC adapter mappings between the VIO partition and the Client Partition.
